National foreword

This British Standard is the UK implementation of

EN 61837-2:2011+A1:2014 It is identical to IEC 61837-2:2011, incorporating amendment 1:2014 It supersedes BS EN 61837-2:2011, which is withdrawn

The UK participation in its preparation was entrusted to Technical Committee EPL/48, Electromechanical components and mechanical structures for electronic equipment

A list of organizations represented on this committee can be obtained on request to its secretary

Foreword

The text of document 49/884/CDV, future edition 2 of IEC 61837-2, prepared by IEC TC 49, Piezoelectric, dielectric and electrostatic devices and associated materials for frequency control, selection and detection, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as

EN 61837-2 on 2011-07-01

This European Standard supersedes EN 61837-2:2000

In EN 61837-2:2011, types of enclosures are renamed to express their features in their names for better understanding The relative comparison of new types with old ones is listed in Table 1 New names of enclosures express configuration type, terminal lead numbers, sizes and arrangement of terminal pads The details of definition are shown in Clause 3: Configuration of enclosures, and Clause 4: Designation of types

Enclosures in EN 61837-2:2011 are based on EN 61240 In EN 61837-2:2011, 27 enclosures are added

to EN 61837-2:2000, as follows:

QCC-12/1407A, DCC-2/1206A, QCC-10/9272A, DCC-4/9070A, DCC-2-8045B, DCC-6/7834B, DCC-6/7050A, QCC-10/7050A, DCC-4/6035C, DCC-2/6035C, QCC-8/5045A, DCC-4/5032A, DCC-4/5032C, DCC-2/4818C, DCC-2/4115C, QCC-8/3838A, DCC-6/3838A, DCC-4/3225C, DCC-2/3215C, QCC-8/3030B, DCC-6/3030A, DCC-6/2520A, DCC-4/2520C, DCC-4/2020C, DCC-4/2016C, DCC-4/1612C, DCC-2/1612C

As a result, EN 61837-2:2011 contains a total of 38 enclosure types, which are listed in Table 1 – Designation of ceramic enclosures

This standard is to be read in conjunction with EN 61240

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights CEN and CENELEC shall not be held responsible for identifying any or all such patent rights

national standard or by endorsement (dop) 2012-04-01

– latest date by which the national standards conflicting

with the EN have to be withdrawn (dow) 2014-07-01

SURFACE MOUNTED PIEZOELECTRIC DEVICES FOR FREQUENCY CONTROL AND SELECTION – STANDARD OUTLINES AND TERMINAL LEAD CONNECTIONS –

Part 2: Ceramic enclosures

1 Scope

This part of IEC 61837 deals with standard outlines and terminal lead connections as they apply

to surface-mounted devices (SMD) for frequency control and selection in ceramic enclosures, and is based on IEC 61240

2 Normative references

The following referenced documents are indispensable for the application of this document For dated references, only the edition cited applies For undated references, the latest edition of the referenced document (including any amendments) applies

IEC 61240, Piezoelectric devices – Preparation of outline drawings of surface-mounted devices

(SMD) for frequency control and selection – General rules

3 Configuration of enclosures

The enclosures of the surface-mounted devices are made of ceramic materials with the terminals of deposited metal film (leadless type) based on descriptive designation system for semiconductors – devices package

The configuration symbols are shown as follows:

– DCC (dual chip carrier);

– QCC (quad chip carrier)

4 Designation of types

The designation of types is shown on four parts as follows:

A: Configuration symbol of enclosures:

– DCC (dual chip carrier);

– QCC (quad chip carrier)

B: Structure of terminal leads: leadless type has no mark

C: Number of terminal leads

– 6 – D: Serial number of both figures

E: Arrangement of terminal land:

– A (arranges to the width direction side);

– B (arranges in the length direction side);

– C (arranges in both the width and the length direction side)

5 Ceramic enclosure dimensions

The dimensions given in this standard apply to all completed SMD-devices for frequency control and selection Only those dimensions which meet the requirements of IEC 61240 are given

6 Lead connections

Recommendations for the lead connections of all completed SMD-devices for frequency control and selection are given in the following individual sheets Lead connections shall always be given in the detail specification
